Rolling start control system/method for semi-automated mechanical transmissions

摘要

A control system and method for a semi-automatic mechanical transmission system (10) is provided for sensing rolling start conditions (OS>REF, GR=N, (CLUTCH MANUAL DISENGAGED=TRUE)) and upon sensing such conditions, allowing operator request for a direct shift into an appropriate rolling start gear ratio (GRRS) determined as a function of current and/or expected output shaft speed (GRRS>/=ESIDLE/OS).
